Title: Improvements in or relating to fluid pressure braking systems
Inventor: FITCH ELLERY RIDDLE
IPC: B60T13/36
Filed: 1950-12-18
Abstract: 681,590. Fluid-pressure brakes. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Dec. 18, 1950, No. 30806/50. Class 103 (i). In a fluid-pressure braking system for a tractor-trailer unit, it is so arranged that should the tractor or trailer service lines become broken or develop a severe leakage, a timing valve 108 on the tractor, adapted to operate in accordance with a predetermined pressure differential between spaced - apart points on the service conduit 50, 52, causes closure of a normally open valve 76 and thus interrupts the fluid flow from the reservoirs 14, 16 on the tractor. The arrangement shown comprises the usual pump 10, main reservoirs 14, 16, front and rear brake chambers 22, 24, and control valve 40 on the tractor; the brake chambers 62 and 64 on the trailer being operated from the reservoir 68 through a relay valve 70. A conduit 116 led off the service line 50 at a point A, forward of the valve 76, connects to a chamber 112 on one side of a diaphragm 111 in the valve unit 108, the chamber 114 on the other side being connected by conduit 118 to point B in service line 52 on the other side of valve unit 76. The chamber 112 is in communication through restricted passage 144 and passage 140 with timing valve member 134, 138 controlling communication between a volume reservoir 104 and an atmospheric port 146 in accordance with the movement of a valvemember 130 caused by deflections of the diaphragm 111. A fluid-pressure actuated valve 106 is effective to connect the reservoir 104 to the chamber 96 of valve 76 if the pressure in the reservoir attains a certain value. The system operates as follows. During normal brake operations the drop in pressure between points A and B causes a moderate flexure of the diaphragm 111 which opens valves 138 and closes valve 134, thus allowing a build-up of pressure through passages 144 and 140 in the volume reservoir 104. The action of the valve member 130 is such, however, that it opens to exhaust again before the pressure in reservoir 104 is sufficient to operate valve device 106 to connect with chamber 96 in the valve unit 76. If the service line 50, 52, 67 should become broken, for instance at the coupling 56, the pressure differential across the diaphragm 111 is then so great that a pressure in reservoir 104 is caused to build up which is sufficient to operate valve device 106. Pressure in chamber 96 of valve device 76 acting against spring 90 then causes the valve 80, 84 to close and cuts off pressure from the service line 52, so that the reservoirs 14, 16 will not exhaust completely and render the brake chambers 22 or 24 ineffective. Specification 488,208, [Group XXIX], is referred to.

Abstract: 521,750. Hydraulic transmission of power AUTOMOTIVE PRODUCTS CO.. Ltd., and PARKER, S. M. Oct. 25, 1938, No. 30842. [Class 69 (ii)] A liquid-pressure remote-control system comprising a pump arranged to deliver pressure liquid to a slave unit through the medium of a liquid actuated byepass valve device which is opened when the rate of delivery of the pump attains a predermined volume to allow part of the said liquid to pass back to the inlet of the pump has such pump delivery through a venturi shaped passage and the reduction in pressure at the throat of the passage is used to open the valve. A pump 41 with reversing valve 42 has line connections 44, 43 with a control member from which lines 45, 46 pass to the slave unit which operates a member 49. When the line 43 is a pressure line liquid passes through a passage 30 to a venturi passage 11 in the throat of which are openings 15 communicating through a groove 17 with a pipe 18 leading to byepass control. Piston 21 which is under spring restraint 22 has a reduced portion 39 adapted to co-operate with two grooves 31, 32 in the valve body. Groove 31 is connected with a main bore by passage 33 and the groove 32 is connected with the return pipe 44 through a valve 34. In this construction the control only operates when line 43 is the delivery line and not when the valve 42 is moved to make line 44 the delivery line. The flow is normal until such time as the pressure drop at the throat permits of the main pressure in the end chamber 28 pushing the valve towards the left against the spring and thereby establishing an opening for byepassing of the liquid into the passage 33, groove 39 and thence by the valve 34 back to the return conduit 44.

Abstract: Absorbent sponge material in sheet form has a base of regenerated cellulose and carries a firmly anchored sheet surface film of a water-insoluble hydrophilic material, the film being interrupted by pores corresponding to pores of the base.  The material may be produced by coating viscose paste which contains a water-soluble pore-forming substance with a layer containing a hydrophilic material capable of becoming fixed thereon and which is water-insoluble or becomes insolubilized in the regeneration process.  The base layer may contain filler material e.g. fibres and a water-soluble pore forming material.  The hydrophilic material may be applied in solution or in powder form say to one or both sides of a web of viscose-based paste.  It may be applied to the surface of an extruded viscose paste prior to passage between embossing rollers.  The hydrophilic material may be a diluted viscose solution, gelatin in aqueous solution, or incompletely hydrolysed polyvinyl alcohol in aqueous alcohol, and may contain a cellulose ether e.g. carboxymethyl cellulose in alkaline solution.  The product after finishing treatments and drying is an artificial chamis leather having a perforated surface film.  In Example 1 an extruded viscose paste is uniformly irrigated through perforated tubes fed by a pump with a diluted viscose containing soda.  The material is regenerated by passing through a bath containing sulphuric acid and sodium sulphate, washed, desulphurised, plasticised and dried to produce a spongy web.
